i7 10 @ZZ whom t may concern Be it known that I, ALBERT BACKUs, a citizen of thc United States, residing at the city 0f St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Pipes, of which the following is a specification.

This invention relates to pipes for smoking tobacco and to cigar and cigarette holders and the like, and one of its objects is to provide a novel means which affords an ample and well-distributed draft from the holder or bowl to the stem; but traps any moisture, tobacco and the like to prevent these deposits from flowing backinto, the

bowl and defiling the tobacco when the pipeis inclined or tilted unduly, and also prevents clogging, so that an easier and more even draft is thereby afforded.

A further object is to provide means for lengthening thepath through the stem traversed by the smoke without increasing the length of the stem; thereby increasing the available cooling surface.

A further object is to provide a novel heatabsorbing deiiecting means for preventing the direct passage of the hot smoke through the stem, whereby the smoke is cooled and mellowed. l

Another aim is to provide means for reinforcing the stem so that the possibilityV of its breakage under ordinary conditions of use is practically prevented.

Another purpose isto provide a stemof such material that the absorption of moisture, nicotine, and other undesirable matter is mitigated or entirely prevented.

There is further contemplated the provision of adjusting means for reducing or auginenting the draft, and, also, the degree of cooling of the smoke, as desired yby the smoker.

Another object is to make the deflecting means of such shape that they may be manufactured economically, and with theV use of conventional tools, and thereby 'facilitate quantity production.

A further ob 'ect is to so construct the aforesaid means that the several component elements may be readily taken apart for inspection and cleaning and for the removal of any accumulated sediment.

The attainment of the aforesaid objects results in the pipe remaining lighted for a longer time when in,use,'because no moisture can soak into the tobacco in the bowl and so retard combustion, and, also, produce a gas which defiles the tobacco aroma and causes assume a rancid odor. It also mitigates or prevents the entrance of nicotinemoisture into the mouth of the smoker.

Various other objects and advantages will appear in the course of the following description. f

The pipe comprises a bowl 1, having a stem 2, preferably integral therewith, and of the same material as ordinarily used for the bowls, such as wood or meerschaum.

A metal tube 3, having its inner end* closed by a wall 4, lines the interior surface of the stem 2, and projects across the bottom of the bowl chamber 5, being preferably held by friction. Apertures 6 in the top side of that part of the stem which intersects the bowl chamber 5 afford communication between the bowl chamber 5 and the interior of the tube 3. The apertures G are preferably at a distance from the wall 4,'so that when the pipe is tilted or inclined unduly, no moisture or sediment deposited in the tube 3 under the apertures 6 can flow back into the bowl chamber, but is trapped in that part of the tube 3 between the wall et and the apertures 6. The tube 3 for this purpose need not necessarily extend from the bowl to the full length of the stem 2; but preferably does because the stem 2 performs the additional function of reinforcing and strengthening the stein 2, which is ofrelatively fragile material, and ralso pro lvides va non-porous lining for the stem 2 which Vdoes not absorb moisture, nicotine, and other y deleterious 'depositsf Furthermore, the tube or lining or stem 3, as well V as the other metal parts having the smoke passages hereinafter referred to, are goed absorbers of heat, and tend to cool and mellow the smoke in its passage therethrough, aswell as to condense the moisture and other harmful elements, which are deposited therein and thereby prevented from reaching the mouth of the smoker, and further prevented from fiowing back into the bowl 1 because of the trapping action of the inner end of the tube 3.

rthe conventional bit or mouth piece 7 forms a continuation of the stem 2, so that in effect the stem 2-and bit 7 may be regarded as one long stem. The bit 7 contains the usual smoke passage 8, which enlarges at its inner end to receive the hollow metal tube'or stem 9, preferably held therein by a tight fit. The tube 9 projects from the lbit 7, and when bit 7 abuts against stem 2, the tube 9 extends into the tube 3 nearly to the wall L1. Tube 9I near the bit 7 is of such external 'diameter as to fit snugly within the mouth of the tube 3, soy that it is retained in place when. inserted there in, but can be easily withdrawn therefrom by pulling on the bit 7. The part of the tube 9 more remote from the bit 7 is of reduced external diameter, so that an annular space 10 is afforded between the inside of the tube 3 and the outside of the tube 9. Av series of transverse flanges 11 on the outside of the tube 9 fit snugly within tube 3, so that annular space 10 is thereby broken into a series of annular compartments. Flanges 11 are flattened or nicked alternately on opposite sides, preferably top and bottom, as best shown at 12 in Figures t and 5, so that communication between adjoinin annular compartments is thereby afforded, `but direct passage of smoke through the stem prevented. rlfhe annular compartment nearest the bit 7 communicates with the interior ofthe ho-llow stem 9 through passages or ports 13 in the bottom side of the tube 9, as shown n Figures -3 and 5.

The inner end of tube or stem 9 is closed by a snugly fitting, but readily withdrawable plug 111, from the innerside of which into the bottom of the tube 3.

a stem 15 projects into the tube 9 to nearly its outer end. Stem 15 is preferably oblong in cross-section, and extends from one side of the tube to the other, preferably in a horizontal plane, thereby forming a longitudinal partition which divides the interior of the tube 9 into upper andlower passages 16 and 17. rTransverse partitions 18 lprojecting from the top and bottom of stem 15 further divide the passages 16 and 17 into a series of compartments 19, 20, 21, 22, 23,24, 25 and 26. Notches 27 in the sides of the stem 15, and transverse apertures 28 inthe stem 15, afford communication between upper and lower passages 16` and 17 and between upper compartments 19, 20., 21. and 22 and lower compartments 23, 24, 25 and' 26 respectively. Either the apertures 28 vor the notches 27 may be used alone, or both may be used together, or any other suitable. means of communication may be substituted therefor. rlhe partitions 18 are fiattened or nicked alternately from opposite sides, preferably from top and bottom, to provide small passages 29 between longitudinally adjoining compartments 16 and 19, 2O and 21, 23 and 24:, and 25 and 25 respectively. The outermost or end partition 18 prevents direct communication of compartment 25 with smoke passage 8, but is notched or flattened at its top to afford communication between compartment 22 and smoke passage 8.

In smoking the pipe, the smoke is drawn from the tobacco chamber 5 through apertures 6 into annular compartment lor passage 10 between tubes or stems 3 and 9, the cu-taway portions 12 of the flanges 11 permitting the smoke to pass from one annular Vcompartment to another, but compelling it however, in its course to wind about the tube 9 because of the staggered arrangement of the several portions`12. `When 4the 'outermost compartment has been reached, the

smoke passes therefrom through holes 13 in the bottom of the stem 9 into the passage 17, from whence it passes to plug 14, and thence through the apertures 28 and Vnotches 27, juxtaposed thereto, into upper passage 16. From passage 16, it enters compartment 19 through port 29, and thence through apertures 27 and notches 28, port 29 to lcompartment 24:, apertures 27 and notches 278 to cOmpartment 20, port 29 to compartment 21, apertures 27 and notches 28 to compartment 25, port 29 to compartment 26, apertures 27 and notches 28 to compartment 22, and from thence over the port 29 in the top of the outermost 'flange 18 into the smoke passage 8 to the mouth of the smoker. The holes 13 are preferably at the bottom of tube 9, so that any moisture or other matter collecting therein may drain therethrough y The numerous flanges, staggered apertures, and other ple time for the condensation and separationy of moisture and other deleterious matter,

which condensation is facilitated because of the cooling and` heat-absorbing character of the metal of which the various stems are fabricated.

When it is desired to' take' the stem apart for cleaning, the bit 7 is withdrawn, removing with it its associated tube 9 and the inserted plug 14. Plug 14 may then be removed by grasping it by the head 30provided for that purpose. Plug 14, and also that part of stem 9 which fits the mouth of tube 3, are, preferably, slightly tapered, being, say, a few thousandths of an inch larger in diameter at their outer ends, so that they become tighter and tighter as they are pushed farther into their respective seats.

It is further to be noted that the arrangement of the several stems one within another provides a longer path through the stem without increasing the length of the stem. Should it be desired to cool the smoke less, or to shorten the length of the smoke path, the head 30 may be turned a half turn, whereby the port 29 of the innermost flange 18 is placed on the bottom, practically short-circuiting the passages 16 and 17 and permitting the entrance of the smoke directly through port 29 into chamber 19.

It is not to be inferred, however,.that this invention is limited in its scope to the precis-e details herein described. For instance,

the tube 9 is not necessarily confined to'a form having annular compartments, but in lieu thereof a spiral groove may be used, or a plurality of spiral grooves, which may, preferably, be of opposite hands and intersecting, as shown at 31 and 32 of the tube 33 of Figures 8 and 9. Furthermore the number of stems, one Within another, that may be employed, is not necessarily limited to the arbitrary number shown in Figures 1 to 7. Figure 9 depictsV an additional tube or stem 34 within the tube k33, and having an annular recess 35 thereon. A plug 36 having a spiral extension 37 may be used therein in lieu of the blade form 15 shown in Figure 3.

Figures 10 and 11 show another modification which can be used instead of the plug 14 and blade 15. It consists essentially of a plug 38 from which projects a rod 39 having lixed thereto a series of flanges or discs 40, which are provided with notches 4l staggered alternately in opposite sides of adjacent discs. Y

Figure 12 depicts an alternative form of trap. The tube 42 has an end wall 43, preferably inclined, through which passes tube 44. It is manifest that, even though the stem be tilted to a vertical position, no moisture can flow back into the bowl, the tube 44 being long enough to extend above vthe level of the usual amount of moisture deposited.

TheAV various parts may be lsuitable materials.

F orfinstance, stem 9 made of any may beformed integral with bit 7, and may Y be molded of bakelite. .j f

Many ofthe improvements herein set forth are capable of uses other thanthose mentioned; and wherever the'word pipe is vrused in the following claims it is in the broad `sense which includes equivalent smoking apparatus, such as cigar and cigarette holders, and smokers rolls. f
